I also have a number of these (and diodes to match). My units are 
rated somewhere around 2.5kV and as many Amps. I ran the figures on 
these based on the di/dt ratings and came up with the disappointing 
result that to run them anywhere near the ratings I would have to 
build a coil which resonated around 10kHz or so. For the last few 
years they have remained sidelined and are waiting for a more 
suitable application.
